Data/SG/Geometry.hs:190:8:
Could not deduce (Eq a) arising from a use of ‘==’
from the context (Geometry rel pt ln,
Coord3 rel,

Fractional a)
bound by the type signature for
valueAtZ :: (Geometry rel pt ln, Coord3 rel, Coord3 pt,

at Data/SG/Geometry.hs:(187,13)-(188,25)
Possible fix:
add (Eq a) to the context of
the type signature for
valueAtZ :: (Geometry rel pt ln, Coord3 rel, Coord3 pt,
Fractional a) =>
ln a -> a -> Maybe a
